Electrical resonance and antiresonance of the electrochemical interface under potentiostatic control: Theoretical considerations

Resonating and antiresonating properties of electrochemical interfaces are explored. A general model for the electrochemical interface is employed in order to derive the conditions when the admittance exhibit a minimum (electrical antiresonance) or a maximum (electrical resonance) at a specific input frequency. The electrochemical interface functions as a band-pass filter under resonance and as a band-stop filter under antiresonance.
